摘　　要：目前对电动汽车再生制动力的控制算法研究主要集中在制动力分配控制算法上,文章提出了一种制动力动态协调控制算法,利用前馈-反馈控制,控制目标是在模式切换过程中尽可能使机械制动系统和电机制动系统的力矩之和满足驾驶员的需求,减小车辆减速度的变化率,保证车辆制动时的平顺性。测试结果表明,所制定的控制策略可以满足驾驶员的需求,保证制动过程的平顺性。：Currently, the researches on the control algorithms of regenerative braking force of electricvehicles are mainly locused on the brake-torce distribution control algorithms. In this paper, a dynam- ic coordinated control algorithm of braking force is presented. The algorithm uses feedforward andfeedback control, and its control objective is to make the total brake of the mechanical braking system and motor braking system meet the needs of the driver as much as possible, reduce the rate of the ve-hicle deceleration change, and ensure the smoothness of the vehicle braking. The test results show that the control strategies can meet the needs of the driver and ensure the smoothness of the braking process.
